Impact of Different Levels of Nitrogen on Growth and Yield of Linseed (Linum usitatissimum L.)

Aim: The current investigation was carried out to analyze the effects of distinct levels of nitrogen on growth and yield for the linseed cultivar Jawahar-7.

Study Design: The experiment consists of randomize block design.

Plan and Duration of Study: The experiment was having three replications which was conducted in Sanjeev Agrawal Global Educational (SAGE) University experimental field which is under the supervision of School of Agriculture; during rabi season 2022-23.

Methodology: In this experiment, 7 treatment combinations including four levels of nitrogen as N1- 0 kg/ha, N2- 60 kg/ha, N3- 10 kg/ha, N4-20 kg/ha, N5-30 kg/ha, N6-40 kg/ha, and N57- 50 kg/ha, respectively. These treatments were treated on the popular variety; Jawahar-7.

Results: Results revealed that the highest plant height (79.21 cm), number of branches per plant (7.78), number of capsules per plant (36.24), test weight (9.96 g), seed yield (17.65q/ha) and stover yield (28.67 q/ha), highest gross return (104541.00 Rs/ha, net returns (81425.00 Rs/ha) and benefit cost ratio (3.87) at maximum crop growth stage was recorded in plots treated with application of nitrogen @ 60 kg/ha followed by the 40 kg/ha, and 50 kg/ha nitrogen application rate. The sequential increase in fertilizer levels of nitrogen gives the higher growth and yield attributes.

Conclusion: Nitrogen supply, N @ 60 kg/ha should be more profitable for the improved growth and development of the crop resulting in enhancement of yield and yield attributing traits which can be economically more beneficial to the farmers.
